I used pH=8.0 PBS binding buffer to banlance the Ni-His tag column. but when i put the protein solution into the column,the protein solution becomes turbid and the resin aggregates together and so the protein buffer could't flow down. How can I do with it .

More info is needed:
* What is your recombinant system?
* How do you prepare your sample?
* Tell me the composition of the buffer that your sample is contained.
* Does your sample contain Calcium? (CaPO4 = insoluble)
* Are you using IDA or NTA technology?
